Testing to see if I need a DPM?

[theflyingpig]

Hi - reading through the post here I understand I need to test the screeded floor in my 60s built flat for moisture . . . . can anyone advice on the tool I need to do this? fore example, would this do?

No, that's not something to measure the moist content of a screed layer with.
That thing works like an indicator for the humidity and temperature of your whole room.

mmm, suspected as much. guess its those way more expensive machines then? is there any DIY way of testing it?

cheers

How old is your screed / concrete layer?

 

[theflyingpig]

thanks for your help woodulike, . . .as old as the flat - but sometime in the 60's. unfortunitly its not level and I want to float a wooden floor on it. . . .

cheers

So the concrete floor is over 40 years old? Do you know (smell) if there is a damp problem?

If not, I don't see a reason why you should need to check the moist in the concrete? Use a Combi-underlayment as moist barrier and sound-insulation and install the floor floating (as you indicated). The DPM of the combi-underlayment will prevent any residue moist (if any!) to reach the wood.

thanks - no there is no damp smell, but I'll use the combi stuff as an underlay. first I've got to get it level! I knocked out a wall between lounge and hall/stairs - and the screed there is higher than in the lounge . . . to the tune of at least 10 mm. . . . too much for self levelling . . .unfortunitly the old hall also goes under the stairs so getting a breaking tool under there to break it out is not going to be easy . . .
any ideas?

thanks again

Hi Huey

Have you checked the stickies in this topic? Some proper info there

 

[theflyingpig]

I did read them, but can't figure out how to proceed . . .

I'm thinking I need to break out the screed where it is too high and re pour it, or have I missed something?

cheers

I think it's best "I hand you over to" Matty (when he's around)
